  • ターゲット情報

    • 機能May contribute to contact inhibition of cell growth and motility by mediating the dephosphorylation of focal adhesion-associated substrates and thus negatively regulating integrin-promoted signaling processes. Induces apoptotic cell death by at least two distinct mechanisms: inhibition of cell survival signaling mediated by PI 3-kinase, Akt, and ILK and activation of a caspase-dependent proapoptotic pathway. Inhibits the basal activity of LCK and its activation in response to TCR stimulation and TCR-induced activation of MAP kinase and surface expression of CD69. Inhibits TCR-induced tyrosine phosphorylation of LAT and ZAP70. Inhibits both basal activity of DOK1 and its CD2-induced tyrosine phosphorylation. Induces dephosphorylation of p130cas, focal adhesion kinase and c-Src. Reduces migratory activity of Jurkat cells.
    • 組織特異性Expressed at high levels in the brain, spleen and liver and at lower levels in the heart and stomach. Expressed in pancreatic and colorectal cancer cells, but not in normal pancreas or colon. Expression in hepatocellular carcinoma is related to the differentiation status of the tumor and expression is inversely related to tumor aggressiveness.
    • 配列類似性Belongs to the protein-tyrosine phosphatase family. Receptor class 3 subfamily.
      Contains 8 fibronectin type-III domains.
      Contains 1 tyrosine-protein phosphatase domain.
    • ドメインThe extracellular domain mediates homodimerization. One or more cysteines in the extracellular domain is essential for the formation of dimers probably by forming a disulfide bond.
      The cytoplasmic domain mediates the interaction with LCK.

    • All lanes : Anti-SAP1 antibody (ab12556) at 1/500 dilution

      Lane 1 : SAP 1 (PTP RH)
      Lane 2 : PTPIA2 beta (PTP RN2)
      Lane 3 : GLEPP1 (PTP RO)
      Lane 4 : LAR (PTP RF)

      Lysates/proteins at 2.8 µg per lane.


      Predicted band size : 122 kDa
      Observed band size : 60 kDa (why is the actual band size different from the predicted?)
      Additional bands at : 90 kDa. We are unsure as to the identity of these extra bands.

      Exposure time : 30 seconds

      The ~60 kDa band corresponds to the size of an SAP1 GST-fusion protein. Reactivity is also observed with GLEPP1 (PTP RO) and LAR (PTP RF). 122kDa is the predicted molecular weight of native SAP1.
